Professional Grade Magnaflow Conv Df 03-05 Crown Vic Passenger Side Ca Upgraded Model [wthCHK1x]

MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 454001 helps keep the check engine light off. DIY installation is easy with the proper tools (no cutting or welding required). With features including mandrel-bent tubing to eliminate flow restrictions and stainless steel construction to resist corrosion, you can have confidence in the quality of this catalytic converter. Using state-of-the-art 3D scanning systems in the design process, the MagnaFlow metrology department ensures this new part to fit and function like the original equipment. Designed to fit the 2003-2005 Mercury Grand Marquis, 2003-2006 Lincoln Town Car, and more, this direct-fit catalytic converter also interchanges with OE part 3W7Z-5E212-AA. Avoid potential exhaust leaks by using the included gaskets to get a proper seal. This replacement part is designed to meet or exceed California Air Resource Board requirements, and has undergone additional testing to comply with CARB guidelines to allow for legal use in California and CARB restricted states, for the listed vehicles.
